If the news item is closely related to the site's content, then perhaps its less important for it to be day-by-day topical, some news items can be relevant to your visitors for longer than a couple of days.
One of my better pulling pages last month was a news item that was put in the month before and then picked up by the google update. I wasn't optimising for any particular keywords, but the title turned out to have a fairly common search with little competition, not traffic doubling or anything, but it all helps. I would have thought longer term more specialised news items would work better for targetted traffic than generic of-the-moment.
Just a thought
